Product Description

If you want to BLOW YOUR STUDENTS' MIND with a lab this Halloween (or during a chemistry unit) by introducing or reinforcing state changes through sublimation, then this is the activity for you!!!

It’s a FUN and EXCITING yet very SIMPLE and EASY teacher demonstration on the sublimation (state change from a solid directly to a gas) of DRY ICE!! My students LOVE it and talk about it all year long! Great for elementary or middle school teachers when learning about physical changes and/or solids, liquids, and gases or as a Halloween Lab! This lesson comes with a step-by-step guide with questions and answers for each experiment and reflection questions which can be graded!! It requires some set up but totally worth the prep!!!

Students will experience the following:

  • Observing white "smoke" sinking
  • Touching and popping white bubbles of CO2
  • Hearing "screaming" CO2
  • Observe bubbles "floating" in an aquarium
  • Drink carbonated apple juice made from dry ice
  • Witness the "world's largest bubble" made with expanding CO2
  • Learn about what dry ice is, what it does, and other uses

Safety Discussion – DO NOT TOUCH THE DRY ICE except with heavy duty gloves. Do NOT store dry ice in an enclosed container. It expands as it sublimates!

Materials Needed:

• 1 lb dry ice per class

• Cooler (wrap the dry ice in a blanket to prevent sublimation)

• Heavy duty gloves for handling

• Warm/hot water (hot plate and beaker)

• Food coloring

• Liquid dish soap

• 2-4 large plastic graduated cylinders

• Bubble wand and bubble solution

• Paper plate (for the bubble solution)

• Large round bowl or witch’s caldron

• Paper towels for clean up

• Large table or desks pushed together covered in newspaper or butcher paper

• 20 gallon Fish aquarium or large clear container

• Quarter or any other coin

• Optional: Small cup of apple juice per student
